How do I make a moving bar?

Basically my character can level up based on experience, how do I make a bar that re sizes depending on how much experience you have? Like a little bar at the bottom of the screen, and when you level up the bar inside of it should be full. Like in WoW.

It´s pretty easy to do if you know how. Here´s a .capx

Basically you connect the objects width to the amount of experience you got. Once it´s full (compare variable to 100 or whatever amount) and execute the level up progress, then set it back to 0.

Cheers

I have made a better version for you

this is the best

try it

you just need to change (exp_need)

and ask me

Actually using your examples I looked and see how you did it, using a different system I created an even better way to achieve the effect, thanks anyways though.
